About Reiss
Reiss is a British contemporary fashion brand founded in 1971 by David Reiss, headquartered in London. The brand designs womenswear and menswear with a focus on refined, modern tailoring and considered everyday pieces — positioning itself in the contemporary upper-mid market between high street and designer. Reiss's product range covers tailoring (a particular strength of the brand), dresses, knitwear, denim, shirts, outerwear, footwear, and accessories. The brand operates extensive UK retail through standalone stores in London and major cities, alongside reiss.com. Reiss has built strong recognition for its tailoring and occasion-wear, with the brand frequently associated with polished, modern British style across professional and special-occasion contexts. The brand received increased attention following styling of public figures, including Catherine, Princess of Wales. Reiss deals typically appear in dedicated end-of-season sales, with the brand taking a more controlled approach to discounting in line with its upper-mid positioning.
Reiss sizing guide
Reiss sizing generally runs true to UK standard, with the brand offering UK sizes 4–18 for womenswear and S–XXL plus chest sizing for menswear. Tailoring is cut close to the body for a refined, modern silhouette, while knitwear and casual pieces tend to fit slightly relaxed.
When does Reiss go on sale?
Reiss typically runs major end-of-season sales in late June/July and December/January, with the brand taking a more controlled approach to discounting between these key periods than mass-market alternatives. Mid-season promotions and Black Friday events also feature on selected ranges.
